[ckan-dev] Can search function work on 'organisation' and 'group' level

Sun Jan 11 23:35:48 UTC 2015

Thanks for your answer. However I got an error after I added your codes into query.py

if not q or q == '""' or q == "''":
            query['q'] = "*:*"
        elif ':' not in q:
            query['q'] = query['q'] + " OR organization:*"+query['q']+"*" + " OR groups:*"+query['q']+"*"

Error: "org.apache.lucene.queryParser.ParseException: Cannot parse \'test OR organization:*test* OR groups:*test*\': \'*\' or \'?\' not allowed as first character in WildcardQuery"',)

I understand Lucene doesn't allow you to start WildcardQueries with an asterisk by default, because those are incredibly expensive queries and will be very, very, very slow on large indexes. How do you overcome this problem?

Cheers

Yes, if you patch the solr config (I also patch the search controller but that might be overkill).

Here is a question concerning the search function of the database.  As far as I can ascertain the search function works on identifying key words from the “dataset” level of the database.  Is it possible that the search function can be expanded to consider the “organisation” and “group” levels as well.

Cheers
